Patterns, or gobos, are widely used by designers in theatre, film, photography and television to create atmosphere, project scenery, and generally enhance the visual impact of their lighting.

Conceived by some of the world's leading lighting designers, the Rosco range presently includes hundreds of standard steel gobo designs.

To insure design integrity the patterns are etched using a precise double-sided process on stainless steel. The result is durable, high quality patterns which will withstand the extreme heat at the gate of ellipsoidal spotlights.

Rosco steel gobos are round to allow for rotation in the gate when aligning the projected image.

The standard "B" size is suitable for most fixtures with a 6" lens when used with a Rosco Pattern Holder or the holders of other manufacturers.

Trimming of patterns, where necessary, can be easily accomplished with a pair of scissors.
